OlL-FEEDING DEVICE.

Specification of Letters Patent.

Patented Feb. 6, 19U6.

AApplication filed June 9,1905. Serial No. 264,387.

citizen of the United States of America, and a resident of Fort Wayne,in the county of Allen and State of Indiana, have invented certain newand useful Improvements in ()il- Feeding Devices, of which the followingis a specification.

This invention relates to improvements in Oil-feeding devices; and theobject thereof is to afford mechanism of simple construction by means ofwhich lubricating-oil will become discharged by force from a fountainthroiigh a series of independent leads'.

The above object is accomplished by the construction illustrated in theaccompanying drawings, in which- Figure 1 is a front View of the deviceshown partially in longitudinal section, and Fig. l is a centraltransverse sectional view of the same.

Similar numerals of reference indicate corresponding parts in bothviews, and, referring now tothe same, 1 is an elongatedhorizontalfountain having a series of independent leads 2, dependingfrom the lower part thereof, each having a central bore 3, which extendsinto and communicates with the fountain.

A revoluble shaft 4 ranges longitudinally through the center of thefountain and is supported in the heads 5 and 6 thereof, and an eccentric7 is rigidly fixed upon said sliaf t approximately in the middle of thefountain, respecting its length. A. worm-wheel ls' is rigidly 'fixedupon'the shaft 4 at a point thereon within the head 6,' and a driving-Worin 9 engages the worin-wheel and actuates the latter, the worin beingmounted upon the driving-shaft 10, which extends into the head 6. Astuffing-box 11 is arranged in connection with the head 6 for thedriving-shaft l0. It will thus appear that when the driving-shaft 1() isrotated the eccentric 7 will accordingly be actuated.

A yoke 12 is arranged in engagement with the eccentric 7 within thefountain and has a hollow vertical stem 13 extending from its upperpart, the stem extending into a guideopening 14, which leads from thetop of the fountain. The lower part of the yoke has a horizontal bar 15in connection therewith, and attached to the bar 15 is a series ofindependent hollow plungers 1G, which extend, res iectively, into thebores 3, of the leads 2 an are vertically movable therein. The said ithe plunger is in its uppermost posit-ion.

4plungers are closed at their tops and open at their lower ends, andeach has a side port 17, which communicates with the fountain when Eachof the leads has a seat 1b.', which faces downward and is annular, and avalve 19is arranged one within each of the leads, each valve having ashoulder 2l), which norinally rests upon the corresponding seat 1S. Thevalves 1*.) are hollow and are open at their tops and closed at theirlower ends and have. side ports 21, which communicate with the lowerpart of the leads beneath the scat ls when the respective valves becomedepressed as hereinafter'described. A spring 22 is arranged onc withinthe lower part of cach of said leads and acts upwardly against thecorresponding valve 1.) to hohl the latter in normal closed relationwith the seat 1S, and an outlet-opening 23 is made at thc lower endofeach of said leads for the discharge of oil therefrom.

Each lead has a glass cylinder .24 in its lower portion beneath thevalve, and sightopenings 25 are made in the leads at points adjacenttheir glass cylinders which render the lower part of their interiorsvisible.

The various hearings of any machine. requiring lubrication may beconnected, respectively, with the lower ends of the leads by means ofsuitable pipes, (not shown,)'so as to receive the discharge of oilthrough the correspondingopenings 23.

The fountain is charged with oil from any suitable sourcey of supplythrough thc projectiontt and stein 13, and when filled andthedriving-shall is set in continuous rotary inotion the plunger' 16 willbe reciproraited vertically in unity, and when in their uppermostpositions the oil in thefountain will gravitate through the ports 17into the respective leads, but will become retarded from furtherdownward passage because of the valves 19. When the plungers are moveddownward, their ports 17 will become closed at the beginning of theirdownward stroke, and the oil contained in the leads between the phingersand valves will be. forced by the downward movement o'f' said plungers,which will have the el'l'ect of pressing the valves downward, so as tocompress the springs 22. Wheii the valves are so pressed downward, theoil above said valves will escape through the ports 21, as said portspass the seats 18, respectively, and fro-in thence the oil willgravitate to and from the discharge-openings 28. It will ap IOS IIO

pear that the oil between the lungers and valves` will be detained abovet 1e valves until the valves become moved downward, and therespectiveiports afford relief for the oil by passing the correspondingseats, and theretore if any of the ports 21 are located at various'distances above the respective shoulders 20, as indicated in dottedoutline at 27, the discharge of oil through the co'rres onding leadswill vary in quantity according y.

Having described my invention, what I,

claim as new, and desire to secure by. Letters Patent,-is-

1Q In mechanism of the class described, a fountain having a4 series ofir. lependent leads communicating with its lo\ er art a series ofplungers Workin in the lea s respectively and each plunger 'aving meansin connection therewith for admission of oil from the fountain into thecorresponding lead when the plunger is inV uppermost position;outletvalves arranged one in each of the leads, and located thereinbeneath the correspondin plun ers; and mechanism lin connection wit thep ungers toiactuate the same.

2. In mechanism of the class described7 a fountain having a series ofindependent leads communicating with its lower' art; a series ofplungers working in the lea s respectively, and each plunger having'means in connection therewith for admission of oil from the fountaininto the corresponding leadwhen the plunger is in uppermost position;outletvalves arranged one in each of the leads beneath the correspondingplungers, each valve being hollow, o en atits top, and closed at itslower end, `an having an annular shoulder which rests a ainst a seat inthe corresponding lead, and aving also a port which affordscommunication for the downward passage of one or more leadscommuniclosed at its top, and open at its lower end,'

and having a side port which affords communication for the passage ofoil from the fountain into the corresponding. lead when the plunger isin up ermost osition; anoutletvalve in each o the lea s at pointstherein below the correspondin plunger; and mech` anism in connectionwit the plungers to ace tuate the same. 4. In mechanism of theclassdescribed, a

' fountain havin independent leads communieating with its ower part eachlead having an outlet-valve; plungers working one in each lead, .eachplun er Ahaving means in connection therewith or admission of oil fromthe- -fountain inte the corresponding lead when the plunger is inuppermostnposition; a yoke' within the fountain, havin connection'witheach plunger, and having a so means in connectionh therewith to guideits movement; and a shaft extending within the fountain and having aneccentric mounted thereon, the latter engaging the yoke to actuate thesame. i
